On some platforms, WCD SPI bus can be shared with other processors
(ex: sensor processor). In such cases, there is need for software
to arbitrate the bus control. Add functionality to perform SPI bus
arbitration.

If we start playback on special hs after record is done and perform
SSR/PDR then playback gets paused. This happens because ANA_TX_DIV2_CLK
which needs to be enabled for special hs gets disabled after record
is stopped. Maintain a count for ANA_DIV2_CLK to enable/disable it
as required.

In wcd-spi driver, the kzalloc is used to allocate memory for TX and
RX buffer. Those allocations are order4 or order5, which could fail
on some kernels. To avoid potential memory allocation failure, the CMA
region is used for those allocations by dma_alloc_coherent API.
